By pressing the specified key indicating the correction of the faulty input character, a cursor directly moves into position on a character line to be stored in a memory, for example, the top of the character line. After the faulty input character is corrected, by pressing the specified key indicating the completion of correcting, the cursor directly moves to the last character input position to enable a sentence C to be inputted again, resulting in permitting an efficient correcting work for the faulty input character. Furthermore, the exclusive key for indicating the correction of the faulty input and the completion thereof set on the keyboard substantially enhances the operational performance of the correcting work for the faulty input.

Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an electronic device such as an electronic typewriter in which characters input from a keyboard can be corrected on a display screen in case of incorrect input, and in particular, the present invention relates to an electronic device such as an electronic typewriter in which characters input from a keyboard can be corrected on a display screen in case of incorrect input. In addition to advanced features, this technology also relates to electronic equipment that has additional functions.

[Prior art]

Conventionally, in electronic typewriters, which are electronic devices of this type, if an operator notices an incorrect input while inputting characters from the keyboard, the operator operates the cursor back key to move the cursor to the position where the incorrect input was made. After correcting the incorrect input, the user presses the relocation key to return the cursor to the position immediately after the last character that has already been input, and continues inputting subsequent characters.

In addition, on typewriters that cannot correct the printed characters afterwards, the printing is performed each time the space key is pressed, that is, for each word, or at the point where the tab key is pressed. The characters input from the keyboard until printing is executed are temporarily stored in the buffer memory, and the stored contents are displayed on the display device, and the above-mentioned correction of the erroneously input characters is performed on the buffer memory.

By the way, when the operator notices the incorrect input as soon as possible, it is more efficient to move the cursor back from the last input position to the position of the incorrect input. If you notice it too late, for example, when you store data to be printed in a buffer by pressing the space key or tab key, if you input the stored contents incorrectly at the beginning, the characters stored in the buffer The correction work may be more efficient if the cursor is returned to the position where the first character of the column is stored before making the correction. That is, since the character string to be re-entered is stored in the operator's head sequentially from the beginning, it is extremely efficient for the operator to re-enter the character string from the beginning.

A control loop is executed that waits for a key on the keyboard KB to be pressed while displaying display data in the J DISP on the display device DIS.

Next, in key operation procedure 2, when the key human power signal KBS from the keyboard KB 11 is inputted, the CPU determines whether the key human power has been input in judgment step S4 in the flowchart of FIG. Signal K
It is determined whether or not the BS is a signal due to pressing of a character key, and in this case, since the signal is a signal indicating pressing of an alphabet key, it is determined that it is a pressing of a character key, and the process proceeds to the next step S5. In step S5, the input character "!" is stored in the position indicated by the data of the cursor pointer CP in the buffer WH, and +1 is added to the value of the cursor pointer CP.

Next, in step S8, the data ``2'' of the cursor pointer CP is compared with the data ``1'' of the end pointer EP, and since the data in the cursor pointer CP is larger than the data in the end pointer EP, the process is performed in step S7. Proceed to the data "2" of the cursor pointer CP.
is stored in the end pointer EP. Then, step S8
The data “work” in the buffer WH is displayed in the memory DIS.
In the next judgment step S9, since the input character is not a space, the process returns to step S2.
The content "WORK" of the display memory DISP is displayed on the display device DIS, and the key manual standby routine of step S3 is executed.

As a result, a display as shown in the column of key operation procedure 2 shown in FIG. 2 is performed on the screen of the display bag Nars.

Next, in step 4, the character key [-1°[al
, [sl are pressed one after another, and the key manual signals KBS to that effect are input one after another, the same control process as in the above-mentioned operation procedure 2 is executed to control each pointer CP, E.
The contents of P and HP, the buffer WB, and the display device DIS are display contents and control contents as shown in the column of operation procedure 4 in FIG. 2, respectively.

Next, in step 5, when the relocation key RELOG according to the present invention is pressed, step S4. Sll and S12, and in step S12, the data of the cursor pointer CP and the end pointer EP are compared, and here, the data "6" of the cursor pointer CP is equal to the data "6" of the end pointer EP. Therefore, the process advances to step 913.

In step S13, head pointer HP data''
3'' is stored in the cursor pointer CP and the process returns to step S2, so the display as shown in the column of step 5 shown in FIG. 2 is displayed and the next key wait is executed.

Next, in step 8, when you press the character key [wl, the same control process as in step 2 is executed, so if you press the character key [wl instead of the character key [wl] that you entered in step 4, The contents stored in buffer 4 and the contents displayed on display device DIJ are replaced (see each column in step B).

Next, in step 7, the relocation key RELOG
When is pressed again, in the flowchart shown in the third figure, step S4. The process sequentially moves to Sll and S12. Then, in step S12, the cursor pointer CP
The data ``'4'' is the data ``6'' of the end pointer EP.
Since the data is different from the cursor pointer C, the process proceeds to the next step 514, where the end pointer EP data "6" is the cursor pointer C.
P, and the process returns to step S2, so that a state in which the cursor position has been moved to the final input position is displayed as shown in the display column of step 7 in FIG.

Next, in step 8, when the space key is pressed, the same control as in step 3 is performed, and printing is performed by the printing device PRT as shown in FIG.

After that, when the return key is pressed, step S3.
